i.MX LPDDR4 Firmware

Hi all,

I see that in the NXP firmware-imx package different versions of the LPDDR4 train firmware is included but I cannot find a Release Note or something else that describes the differences. Does anyone know what is the correct version to be used?

Here is the content of the latest NXP release: lpddr4_pmu_train_1d_dmem_201904.bin lpddr4_pmu_train_1d_dmem_202006.bin lpddr4_pmu_train_1d_dmem.bin lpddr4_pmu_train_1d_imem_201904.bin lpddr4_pmu_train_1d_imem_202006.bin lpddr4_pmu_train_1d_imem.bin lpddr4_pmu_train_2d_dmem_201904.bin lpddr4_pmu_train_2d_dmem_202006.bin lpddr4_pmu_train_2d_dmem.bin lpddr4_pmu_train_2d_imem_201904.bin lpddr4_pmu_train_2d_imem_202006.bin lpddr4_pmu_train_2d_imem.bin

Thanks
